W., C. TURPIN ET AL CLEAN-OUT Y Filed April'O, 1946 IN VEN TORS C Tur/vin Patented Dec. 28, 1948 UNITED ori-ics William C'. '.Elll'pinV andglohn. Turpin, Newport-News', Ya.

This invention relates to improvements inY a clean-out. Y of the character used particularly for sewers.

Sewers frequently become clogged,- leapeiallyl whenconstructed of .small diameter, such as iordinarily cast iron or terracotta pipe. It has been the practice heretofore to provide clean-out boxes or a clean-out Y at intervals along the sewer pipe and extending te thesurae of .the ground, so as to permit the pipe to be cleaned out by the insertion of a wire or cable therein for the purpose. l The usual type of clean-out provided heretoA fore has employed a pair of Y joints facing toward each other and so connected with the sewer line that access may be hadA theretov for the purpose. These have not been-entirely satisfactory, however, due to -the'difculties of gettingk access to the sewer, the ineffectiveness of cleanout provided therefor, and the extra expense of using a plurality of pipe connections extending to the surface of the ground.

The object of this invention is to improve-the construction of the clean-out Y to permit the vuse of a single connection extending to the surface of the ground and yet provide for the effective and practical cleaning out of the sewer line by the usual cable or wire. if

This object is accomplished in thevprefer-red embodiment of the invention by the construction of the clean-out Y with an upper portioniconstructed to receive a joint of pipe that extends to the surface of the ground and having downwardly inclined and widely flaring sides so constructed as to direct the clean-out cable or wire into the respective ends of the Y thence to the respective sections of sewer joined thereto.

This form of the invention is illustrated generally in the accompanying drawings in which:

Fig. 1 is a vertical sectional view through the clean-out Y connected in a sewer line and having a pipe connection shown in elevation extending to the surface of the ground;

Fig. 2 is a cross section therethrough on the line 2-2 of Fig. 1; and

Fig. 3 is a similar view on the line 3-3 of Fig. 1.

The invention is shown as applied to Aa sewer pipe line, one section of which is indicated generally by the numeral I, and another section is shown at 2. These pipe sections may be constructed either of the usual cast iron pipe, as shown at l, or of terra cotta pipe, as shown at 2, or both may be used in a single line. At one or more desired points in the sewer line, it is 2 mains.; (o1. css-2m.)

desirable te have a.v clean-out. connection .that entends` toyfthesurfaeeof the ground. For this purpose, a. pipe 3 .is `adzatpted to extend. down wardlar :from` the sur-faceof the ground, where it is. provided` with an open. yupper end. 'that is adapted to be closed by a plug or adapter gen erally inriicfarted,at t. This piugmay be remeved from :the pipe 1 when itis desired to get accese to the-:sewer` Theapipe 3 vis 4joined to the sewer line: I.-2 byA meansof-a Y :generally-designated at, 5. Y .E has :an `[awning centiiniuously therethrough a lengthwise 'directicziny as designated. `gener-ahyat t and at mimoaite-` lends, of the opening the of the Y is formed with male and female cori-r necting portions 'I and 8, respectively, inthe imm of `pbl-igqgaxtid vsocket adapted to'finteriit withcomplementary portions .ei tbepipe` .sections i andi.

. Intemedinte the length 'the :body portion of the Y 5 isa Abranch connection 9, that is provided with a. socket I0 to receive the lower end of the pipe 3. The opposite sides in a lengthwise direction of the branch connection 9 are widely flaring at II, substantially at an angle of 45 to the longitudinal axis through the opening 6. The upper sides of the respective sloping portions II are semi-circularly curved, as shown in Fig. 2. The purpose of these flaring sides is to guide the clean-out cable or wire into the respective end sections of the sewer and thus effectively cleanout the ,entire length of the sewer and yet by means of a very simple and inexpensive structure for the purpose. By reason of having opposite sides of the Y as sloping at I I, it is possible to direct the clean-out cable or wire in either direction.

The structure thus described, presents a greatly simplified formation structurally, thus tending toprovide for low cost of manufacture. However, the greater advantages become apparent when the structure is in service. One of these advantages is directly due to the body formation which presents the oppositely flared walls II extending at a definite angleapproximately 45- to the axis of the opening which receives the connection 3 leading to the ground surface and which may be considered as the stem opening of the connection. A5 is indicated in the drawings, the inner face of each of the ilared zones is practically linear in type in the direction of length of the wall portion and with the wall portion curved in transverse section. As a result, the juncture or meeting point of a wall portion II and the upper zonal wall of the outlet openings to the sewer connection presents a definite angular rewith the outward movement controlled by the angle of the face so that liability of any undesired shaping of the implement will be prevented.

The greater advantage comes, however, from the fact that when such implement--advance'fend'" reaches the lower limit of the face, suchend advancing in a direction to enter:thercontentfof the sewer end zone of the connection at an acute angle to the axis of such end zone, with thel result that the implement end zone will tend .to traverse such contentin the direction 'of such axis, thus rendering the implement especially ef;v fective in breaking up theclogged condition,sin`ce the advance `end is being made 'active' with'k the core `zone of the obstruction ratherfthan the periphery; 'v I r Since less severev clogging will permit such tra` versing action within the body zone, it can loe understood that through the presence of the deiinite angularfrelationship at suchjunction or meeting point, the I cleaning implement"fwill'becaused to traverse the content'in the direction of the corel axis under al1 conditions of service,'thus ensuring effective clean out action under al1 con`l ditions.
